This invention appertains to new and useful improvements in valves and more particularly to a high pressure valve.

The principal object of the present invention is to provide a high pressure valve of simple construction and easy operation.

Another important object of the invention is to provide a valve which will be substantially foolproof in operation and which will take care of high pressures without likelihood of leak developments.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational View of the valve.

Figure 2 represents a vertical sectional view taken substantially on line 2-2 of Figure 1.

Figure 3 represents an end elevational view of the valve element.

Figure 4 represents a perspective view of the stem.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the device consists of a shell 5 internally threaded at its lower end as at 6 to receive the reduced threaded portion 1 of the internally threaded adapter 8. The reduced portion i has the annular valve seat 9 mounted thereon, this valve seat being of resilient material and provided with a beveled seating face Ill and a circumferentially extending groove II in its upper portion. The outlet adapter l2 which is formed as an integral part of the shell 5 is internally threaded as shown in Figure 2. The upper end of the shell 5 is internally threaded and below these threads and at the inner side of the shell is the circumferentially extending shoulder 13 forming a part of a stufling box which includes the resilient packing ring l4 and the sleeve or gland l5 which is threadedly engageable with the internal threads at the upper end of the shell 5. The top of the shoulder l3 as Well as the lower end of the sleeve I5 is beveled to produce the usual distorting action of the ring l4. Slidably disposed through this stuffing box is the shank 16 carrying the valve head I! at its lower end. This shank is of tubular construction and has a threaded opening through its upper end to receive the inverted L- shaped stem l1.

A yoke including a pair of leg members l8-l8 is secured to the shell 5 by passing bolts [9 through the lower ends of the legs. The upper end portions of the legs converge inwardly and are connected with one end of the lever 20 by 5 passing a pin 2! through the upper portions of the legs I8 and one end of the lever 26.

The last mentioned end of the lever 25! is provided with a diverged member 22 in the form of a yoke as shown in Figure 2 which straddles 10 the upper end of the stem I1. A pin 23 is fed through the lower portion of the yoke 22 and through the opening 24 in the stem I1, thus pivotally connecting the member 22 with the stem ll.

A cross member 25 bridges the legs lB-IB and a set screw 2% is adjustable therethrough to coact with the stem I'I.

Referring to the valve head [1, it will be seen that the lower portion is provided with a circumferential bevel 21 in engagement with the beveled surface ID of the resilient valve seat 9 and depending circumferentially extending flange 28 for engagement into the circumferential groove H of the resilient seat 9.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit of the invention as claimed hereinafter.

What is claimed is:

A high pressure valve comprising a shell, an adapter extending into the lower portion of the shell, a resilient seat mounted on the adapter and provided with a circumferential groove therein and a beveled valve seating surface, a stuffing box in the upper portion of the shell, a valve element provided with a beveled surface for engaging the beveled surface of the seat and a depending circumferentially extending flange for engagement into the said groove of. the seat, said valve element being provided with a cylindrical shank slidably disposed through the stuifing box, the upper portion of the shank being provided with an inverted L-shaped extension and a lever rockably mounted on the shell and pivotally connected to the upper end of the extension.
